UNITED STATES DANIEL H. YOUNG, OF MANCHESTER, IOWA.

HUMIDIFIER.

Application filed February 10, 1919.

T 0 all whom it may concern Be it known that I, DANIEL H. YOUNG, a citizen of the United States of America, and a resident of Manchester, Delaware county, Iowa, have invented certain new and useful Improvements in Humidifiers, of which the following is a specification.

My invention relates to improvements in humidifiers, and the object of my improvement is to supply in humidifiers which comprise a boiler with included electrical heating means for its contents, a special type of boiler and electrical heating means therein wherein the heating means is susceptible to adjustment and is adapted to coact with the boiler in such a manner as to eonduce to greater eiliciency of said heating means under desired conditions.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawing, which is a front elevation of my improved humidifier. with parts thereof and of its supporting means in vertical longitudinal medial section.

The said supporting means may be of any desired pattern, but, as shown comprises a hollow base 13 connected to or bracketed from a back-plate 16. The base has in its to an opening 14.

The numeral 3 denotes a boiler which is supplied with water automatically, that is by an air-pressure device in a well-known way. This device consists of a reservoir, having a single receiving and delivery neck, the reservoir 19 being inverted after filling with its neck inserted into the top of an open vessel 18 to fit same and deliver its contents thereinto asdetermined by air-pressure. conduit 17 affords communication between said vessel 18 and the lower part of the boiler 3.

The boiler 3 is of an inverted cone shape with top closure 4 centrally orificed to receive an insulating sleeve 5, the latter also centrally orificed to receive a vertical stem 1 or conductor member on whose lower part is fixed a hollow electrode also in the form of an inverted cone positioned within said boiler concentrically. The angle of inclination of the electrode 2 may be the same or different than the angle of inclination of the said conical boiler without departing from my invention. The cone 2 is seated in the lower part of the boiler in spaced relation thereto.

Specification of Letters Patent.

Patented Oct. 26, 1920.

Serial No. 276,017.

A rectangular loop-shaped hanger 12 is fixed under the opening 14 in said base 13, and in this hanger is reinovably positioned and supported a casing containing a socketed mass of insulating substance 11. In this socket is fitted a sleeve 10 interiorly threaded to receive the footer lower extremity 9 of sai foot 9 being exteriorly threaded to be adjustable relative to the fixed sleeve 10. The lower end of the boiler 3 is supported on said insulation and easing such wise that the stem 1 remains insulated from the boiler.

The upper end of said stem '1 projects upwardly from the insulating sleeve ,5, and on this projecting end is fixed a knurled disk 6 for use in turning the stem. On the upper tip of said stem may be adjustably mounted a bi'ndingscrew 7 for the end of an electrical conductor 22 leading to one pole of a battery or other terminal of a generator of electric current 21, said conductor containing a switch 23. The other terminal of said source of current 21 is connected with the conducting shell of said boiler 3 by means of the conductor 20. In the upper part of the conical boiler 3 is a delivery port for steam delivering into a funnel 8.

The full lines show the position of the conical electrode 2 when in its lowermost position in said boiler, at which time the water level in the boiler in the interspace of the boiler and electrode is located as indicated h the dotted line a. This is the usual position of the electrode when the humidifier is in active operation. It is desirable, however, to lower the water resistance at the initiation of the operation,

to prevent blowing out a fuse. I effect this desired result by turnin the stem to ad justingly move it upwardly to an approximate position in the boiler indicated by the dotted line 0. This results in widening the interspace 15 of the electrode and boiler, and lowers the level of the water in the boiler to the level indicated by the dotted line b. It will be seen that now a much diminished surface of the electrode is immersed in the water, though the interspace 15 is not much widened, and if the circuit is now closed, there is a reduction of resistance. The electrode me then be returned to its first position, without blowing out of a fuse, where its more largely immersed surface acts on the thinner stratum of water to quickly bring the water to the conducting stem 1, said a boiling point, the circuit being eompleted through the water from the electrode to the boiler shell. Generated steam is permitted exit by way of the funnel 8 to be diesemr nated throughout a room or other inclosure, to Froperly humidify the air therein.

he conical electrode 2 has advantage of permitting adjustment rel tive to the boiler and the water therein, 50- that the heating of the water may he graduated as desired by mere adjustment in position of the electrode. Hence the water may be heated as desired to furnish steam as rendered necessary by the conditions of its use. While I have shown an' electrode of conical shape in coaction' with a corneal boiler, I wish it to berelearly understood tlfiat my invention emprises variations in the shapes of either 01 both which will insure the above desired reeiilts in practice. Having desc' ibed my invention; what I claim as new,- and desire to seizure by Letters Patent isi 1. A nested pair at spaced inverted conithe further cal electrically conducting terminal parts, the inner artbeing a closed hollow body, the outer part bein of greater altitude than the inner art an cl closed at the top, the inner part eing vertically adjustable within said outer part, and the outer part havin an exit-port at the top for va'po'r generate therein.

2. A nested pair of spaced inverted conical electrical confirming termite} parts, the inner ert being of let's" itltitu'de than the outer art and vertically adj esteem to vary the width of their inteiepace, said outer part being closed me having an ear-itport i'il its upper end; the larger upper end of theou't'er eerving' 91S aeonteiaer for vapor generated from a li irid mthe'i'nterspace of said closed circuit with rent,
